Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...l against intruders, yet also contain molecules to recognize and communicate with other cells or get nutrients. Cells also communicate with one another via small, membrane-bound vesicles that contain proteins or other molecular cargo. When delivering their goods, vesicles from one cell fuse with the outermost ...

A new plant-bacterial symbiotic mechanism promising for crop applications

...orated by the bacterium which enables the plant to recognize it, by molecular recognition, thereby allowing the microorganism to penetrate inside the plant by the root hairs. The finding raises the question as to what signalling pathway Bradyrhizodium might use to gain entry to the plant and set off nodulat...

'Nurse cells' make life and death decisions for infection-fighting cells

...e function of T cells produced by the thymus is to recognize harmful invaders. Once invaders have been identified, T cells then attempt to eliminate disease-infected cells. "In early studies, it was suggested that thymic nurse cells only removed non-functional thymocytes," said Eve Barak, program director i...

To recognize that what we put into our environment has potential pandemic effects on pregnancy outcome and possibly on child development is a momentous observation, which hopefully will help transform the way humanity cares for its world," said James Lemons, M.D....

The quest for an effective HIV vaccine presents new possibilities, challenges

...xposure, the immune system develops the ability to recognize the specific microbe and can protect the human body against it if it reappears. HIV, however, has thwarted scientists?efforts thus far to develop a classic preventive vaccine for the virus because of its ability to integrate into target cells and eva...

In addition to genes implicated in intracellular signaling and intercellular interactions, a number of genes involved in...

Gut research yields new anti-cancer approach

...lls have evolved to include "efflux" proteins that recognize standard chemotherapies as foreign, and "pump them out" of tumor cells. Even for breast and lung cancer, the tumor types for which Taxol is most used, nearly 100 percent of these tumors eventually become resistant, said Alok A. Khorana, M.D., assista...
